[object Object]

[object Object][object Object]undefined[object Object]

• This API performs an element-wise arctangent operation on the input tensors self and other. (self indicates the y coordinate, and other indicates the x coordinate.)

• Formula:

  $$out_{i}=tan^{-1}(self_{i}/other_{i})$$

[object Object]

[object Object] and [object Object] implement the same function in different ways. Select a proper operator based on your requirements.

• [object Object]: An output tensor object needs to be created to store the computation result.
• [object Object]: No output tensor object needs to be created, and the computation result is written in place to the input tensor's memory.

Each operator is divided into two phases (../common/two-phase-api.md). You must call aclnnAtan2GetWorkspaceSize or aclnnInplaceAtan2GetWorkspaceSize to obtain the workspace size required for computation and the executor that contains the operator computation process, and then call aclnnAtan2 or aclnnInplaceAtan2 to perform computation.
